Using Adobe Fill & Sign as a Standalone App

Adobe Fill & Sign can be used entirely offline as an independent application, bypassing the need for an Adobe account login.

Because Adobe Fill & Sign operates independently from Adobe Acrobat Reader and Document Cloud on Android, it does not mandate a sign-in. However, this independent operation means your signatures, filled text, and modified PDFs will not automatically sync across your devices or overwrite the original file in Acrobat Reader.

Open the Application

Launch the Adobe Fill & Sign app on your Android device. If prompted to sign in, bypass or skip the login screen.

Select Your Document

Tap 'Select a form to fill out' and browse your device's local storage to open the specific PDF file you want to edit.

Fill and Sign

Tap anywhere on the document to insert text fields. To sign, tap the 'Signature' icon at the top of the screen to draw and insert your personal signature.

Export the File

Since changes do not auto-save to the original file, tap the 'Share' or 'Send' icon upon completion to manually save the modified PDF to your device or send it via email.

Synchronization Limitation: Reinstalling the app or signing into Acrobat Reader at a later time will not synchronize the data or signatures you created in Fill & Sign. Always make sure to export and save your completed forms.

Frequently Asked Questions

Why aren't my signatures syncing between Adobe Fill & Sign and Acrobat Reader?

Adobe Fill & Sign operates as a standalone application on Android. Since it does not require an account sign-in, its local app data and saved signatures cannot sync through Adobe Document Cloud or communicate directly with Acrobat Reader.

Does Adobe Fill & Sign automatically save over the original PDF file?

No. Any changes made within the Fill & Sign app are not automatically saved to the original PDF. You must manually use the Share or Send options to save a new copy of the filled document to your device.

Can I use the Adobe Fill & Sign app completely offline?

Yes. Because the app bypasses the need to sign into an Adobe account, you can select local PDF files, fill them out, and apply your signatures without needing an active internet connection.
